DQE(f) of four generations of computed radiography acquisition devices

Measurements were made of the MTF( f ), NPS( f ), and DQE( f ) of four generations of computed radiography (CR) imaging plates and three generations of CR image readers. The MTF generally showed only a minor change between generations of plates and readers, but the DQE( f ) has improved substantially from a very early plate/reader combination to a more recent one. The DQE in the more recent plate/reader combination is 1.3× greater at low...
